Got stuck in the same issue, resolved with EditorApplication.delayCall delegate that's called after the inspector updates. Hope it's helpful!

Resolution Note:
Thank you for reporting this bug. As we transition to focusing on UI Toolkit, we can only address major issues or regressions in IMGUI. Fixing this specific bug would risk regressing IMGUI too much.
Consider using a flag to delay the opening of the modal window until after you close the Vertical group.
